The application of appropriate personal protective equipment for respiratory protection to health care workers is a cornerstone for providing safe healthcare in emergency departments. We investigated the protective effect and usefulness of loose-fitting powered air-purifying respirators (PAPRs) during chest compression. ⋯ The loose-fitting PAPRs provided sufficient respiratory protection without disturbances during chest compression.

Multicenter Study
Diagnostic accuracy of combined WBC, ANC and CRP in adult emergency department patients suspected of acute appendicitis.
To assess the sensitivity, specificity, and negative predictive value (NPV) of normal total white blood cell count (WBC) and normal absolute neutrophil count (ANC) combined with a normal proprietary C-reactive protein (pCRP) level in adult emergency department (ED) patients with abdominal pain suspected of possible acute appendicitis. ⋯ The combination of normal WBC and ANC with normal pCRP levels exhibited high sensitivity and negative predictive value for acute appendicitis in this prospective adult patient cohort. Confirmation and validation of these findings with further study using commercially available CRP assays is needed.

Identifying patients at imminent risk of death is a paramount priority in combat casualty care. This study measures the vital sign values predictive of mortality among combat casualties in Iraq and Afghanistan. ⋯ Casualties with a systolic blood pressure <112 mmHg, are at high risk of mortality, a value significantly higher than the traditional 90 mmHg threshold. Our dataset highlights the need for better methods to guide resuscitation as vital sign measurements have limited accuracy in predicting mortality.

The objective of this study was to determine if performing a methicillin-resistant Staphylococcus aureus (MRSA) nasal screen in the emergency department (ED) decreased general medicine patient exposure to anti-MRSA antibiotics for pneumonia. ⋯ Performing a MRSA nares screen in the ED for patients diagnosed with pneumonia, initiated on anti-MRSA antibiotics, and admitted to a general medicine floor did not decrease duration of anti-MRSA antibiotics. At this time, ED providers do not need to consider a MRSA nasal screen in the ED for patients being admitted to general medicine, although larger studies could be considered.

Many victims of drowning fatalities are lay-people attempting to rescue another. This review aims to identify the safest techniques and equipment (improved or purpose made) for an untrained bystander to use when attempting a water rescue. ⋯ The expert recommendation of the safest technique for a lay-rescuer is to attempt rescue using a pole, rope, or flotation equipment without entering the water. However, despite the recommendations of non-contact rescues from land, there is a global tendency to attempt contact rescues in the water, despite a lack of evidence on which technique, procedure or equipment contributes to a safer rescue. Training strategies for lay-people should be considered.
